The MA 200 Mono Power Amplifiers - the ultimate SET

The way of Kings...

The legendary 300B in perfection with our MA200 driven by the famous DHT 46 Triode connected. The output and Interstage Monoblock MA200 Parallel-Amplifier is a uniquely different amplifier — it is our highest and most extreme expression of single-ended amplification, exclusiv for the true connoisseur audiophile. The output and interstage transformer design style is is in-house made by TSS Switzerland for our TSS top of the line MA200 amplifiers used. Very importantly, rather than an additional tube driver stage, the output transformer also our interstage transformer additionally offers a further high light, namely the galvanic separation of two stages, which represents an immense sound improvement., for ultimate musicality and authority, providing a level of realism and detail that you may not have experienced.

Pure SET magic

The MA200 is a so-called dual-circuit power amplifier with 6 mains transformers. Each section has its own power supply with total of 6 power supply transformers. All of this is housed in a MA200 enclosure with just a single 25 ampere power connection and 1 x on/off.

Output transformers

For each monoblock:1 x filament power transformer / driver 46 triode1 x high voltage power transformer / driver 46 triode1 x filament power transformer 300b power triode1 high voltage power transformer 300b power triode2 x power Transformer and 2 x rectifier tube

Craftsmanship and innovation

Further, 6 filter choke coils are installed 3 per section for absolutely safe operation.4 x interstage transformers and 1 output transformer all with a large 300% oversized E-core which is reflected in breathtaking sound characteristics, we are quite sure that our MA200 is unique. Traditional craftsmanship and innovative technology – the best of both worlds. The MA200 is full transformer coupled and all DHT Triode power Amplifier with a sound caractaristic that you probably you can't imagine if you have not yet heard the MA200. The 300b driven by a 46 triode conected the royal road in amplifier construction.
